The internet of things node data refers to internet of things data acquired by each internet of things terminal (or called node) deployed in an internet of things scene in real time or periodically.
Specifically, in an application scenario, the cellular network backhaul module and one or more internet of things communication modules of different communication systems to be used may be inserted into the MINI PCI-E interface socket 18 in the form of a plug-in card, and after the control circuit 100 of the entire internet of things gateway is powered on, the internet of things communication module wirelessly collects internet of things node data from each internet of things terminal in the application scenario, and outputs the internet of things node data to the main control chip 12 from the MINI PCI-E interface socket 18, so that the main control chip 12 performs corresponding conventional processing and aggregation on the received internet of things node data, and outputs the internet of things node data to the cellular network backhaul module from the MINI PCI-E interface socket 18, so that the cellular network backhaul module wirelessly transmits the data to an upper server to which the internet of things gateway belongs through the cellular network, and the upper server performs subsequent analysis processing.

In the face of the Internet of things terminals with various communication modes, various Internet of things gateways do not need to be deployed, the network distribution cost is greatly saved, the energy consumption and the Internet of things upgrading cost are reduced, and the purpose of greatly reducing the application cost is achieved.
In one embodiment, the number of the MINI PCI-E interface sockets 18 may be two or more, and each MINI PCI-E interface socket 18 is electrically connected to the main control chip 12.

Therefore, by means of an extensible setting mode, the plurality of MINI PCI-E interface sockets 18 are arranged, plugging and unplugging of more Internet of things communication modules can be conveniently supported, the extension performance of the control circuit 100 of the Internet of things gateway is improved, and the applicability of the Internet of things gateway to which the control circuit 100 of the Internet of things gateway belongs is effectively improved.
Referring to fig. 2, in an embodiment, the control circuit 100 of the internet of things gateway further includes a POE power supply circuit 11, a first ethernet PHY chip 13, and a backhaul port socket 15. The POE power supply circuit 11 is electrically connected to the first ethernet PHY chip 13, the backhaul network port socket 15, and the main control chip 12, respectively. The first ethernet PHY chip 13 is electrically connected to the backhaul port socket 15 and the main control chip 12, respectively. The POE power supply circuit 11 is configured to supply power to the backhaul network port socket 15. The first ethernet PHY chip 13 is configured to output the internet of things node data output by the main control chip 12 to the backhaul port socket 15.

It can be understood that the POE power supply circuit 11 is an existing POE power supply module in the field, and may be any type of POE power supply module on the market, and specifically may be selected according to the power supply requirement of the backhaul network port socket 15.

Specifically, in practical applications, when there is a fixed network backhaul network in an internet of things scene, the main control chip 12 may also connect to the wide area network through the first ethernet PHY chip 13, so as to perform corresponding conventional processing on the received internet of things node data, and transmit the data to the wide area network through the first ethernet PHY chip 13 and the backhaul socket 15, and transmit the data to the upper server through the wide area network. Therefore, the method can be complementary with a cellular network return module in practical application, and application coverage of more internet of things scenes is realized. For example, when there is no fixed network backhaul network in the scenario of the internet of things, and only there is a mobile data network (i.e., a cellular network), the main control chip 12 may transmit the processed data of the internet of things node back to the upper server through a cellular network backhaul module.

The second ethernet PHY chip 17 and the debug port socket 19 may be soldered to the same PCB substrate as the main control chip 12; the second ethernet PHY chip 17 and the debug port socket 19 may also be soldered on an independent PCB substrate, for example, the second ethernet PHY chip 17, the backhaul port socket 15, and the POE power supply circuit 11 are soldered on the same PCB substrate, and the specific setting mode may be determined according to actual application requirements. The debugging parameters refer to test parameters determined by the upper layer server for different scenes of the internet of things, and are used for enabling the main control chip 12 to automatically complete initialization configuration, setting parameter change or performance test and the like for different scenes of the internet of things, and the debugging parameters can be specifically determined according to the debugging requirements of the upper layer server on the control circuit 100 of the gateway of the internet of things in practical application.
Specifically, in the practical application process, the main control chip 12 may also access the wide area network through the second ethernet PHY chip 17 and the debugging port socket 19, so as to receive debugging parameters issued by the upper server, so that the upper server may remotely debug the control circuit 100 of the internet of things gateway, so that the control circuit 100 of the internet of things gateway can be used in the internet of things scene for the first time, or when the original internet of things scene is transferred to another different internet of things scene for use, the debugging can be quickly completed to adapt to the currently used internet of things scene; the control circuit 100 of the internet of things gateway can be remotely controlled by the upper-layer server conveniently, and special debugging personnel do not need to be arranged to debug on site, so that the application cost is further saved.
